[Boost-users] Re: Re: serialization

Hmm, are we serializing through a base class or a derived class? If through a base class has the derived class been "registered" via register(..) or via BOOST_CLASS_EXPORT? Robert Ramey Damien * wrote:

has anyone seen this compile error before, and know how to fix it?

im trying to serialize a polymorphic class that has a pointer to another class of the same type in it. if i comment out that line in the serialization function, the error goes away.

is MyClass abstract? That is, does it have a pure abstract function in it ( func() = 0;)? Check BOOST_IS_ABSTRACT in the documentation.

MyClass is not abstract. it has virtual functions, but no pure virtual functions. if i use that macro however, the error goes away, but i then get this runtime assertion failure when it tries to serialize out.
